So I need strategies for two bosses: the New Year Demon and
I have a suspicion you're supposed to fight NYD on, well, New Year's Eve/Day, but I'm not sure about the final boss.
Just beaten the final boss first try, if you still need help with it, heres my formation for every boss:
Yourself: Get your max sp up to at least 140 with mana stones or the phantom heart, then just activate your boundary break and survive till you have 400 sp to do your finisher, the unbound ___ attack. with finisher i mean this shit does like 7k to 9k dmg. I recommend using floras heart too, for slowing her down. you dont need to do an attack except from time to time floras heart if you feel like you need it, because those waste sp and you want to grind fast sp. you just stay in def.
Aegis: At the start use sanctuary and after that use power counter on every ally, and then just cover till one of the other things runs out, then use it again, etc.
Mana: immidiately use force shield on every ally starting with yourself, after that you just spam your abilities; use common heal when someone gets low, medical care if u or your allies get any debuffs, and if dont need to heal, remove debuffs or reactivate shields, use negative vision (again to slow her down) or use your primary ability to reduce her accuracy.
You should be able to beat her first time with this guide, and of course other guys that have problems with the final boss or enemys earlier on can just follow it too.
